Acid base and sorption properties of phosphorus containing polymeric sorbent

AbstractIn the present work, the acid base properties of phosphorus containing polymeric sorbent on the basis of polybutadiene have been investigated using the method of potentiometric titration and sorption properties in relation to copper ions have been studied. It has been revealed that the investigated sorbent has polyfunctional nature and for every type of functional groups, the pK ion values have been calculated. It has been established that maximum copper ions sorption is observed at pH 6. Sorption isotherm, processed by Langmuir and Freundlich models, allows us to conclude that the copper ions sorption occurs on energetically homogenous functional groups with the formation of monomolecular layer of sorbate.
